  • Product description

    The test piece is clamped between two airtight circular gaskets of known dimensions. The absolute air pressure at the side of the test area is equivalent to atmospheric pressure. The difference in pressure between the two sides of the test piece is maintained at a small but substantially constant value during the test. The flow of the air through the test area in specified time can be calculated.
